NSPECTING AND HANDLING THE UNIT
The units are packed in a wooden crate and attached on a wooden
pallet.
At delivery, the package should be checked and any damage should
be reported immediately to the carrier claims agent.
When handling the unit, take into account the following:
1 Fragile, handle the unit with care.
Keep the unit upright in order to avoid compressor damage.
2 Lift the unit preferably with a crane
and 2 belts (1) of at least 8 m long.
3 When lifting the unit with a crane,
always use protectors (2) to prevent
belt damage and pay attention to the
position of the unit's centre of gravity.
4 Bring the unit as close to its final
installation position in its original
package to prevent damage during
transport.
U
NPACKING AND PLACING THE UNIT
1 Remove the wooden crate from the unit.
Remove the four screws fixing the unit to the pallet.
2
3 The unit must be installed on a solid longitudinal foundation
(steelbeam frame or concrete) as indicated in figure 4.
NOTE Maximum height of the foundation is 150 mm.
4 Lift the unit from the pallet and place it on its installation position.
5 Fasten the unit in place using four anchor bolts M12.
6 Remove the upper and lower service plate.
7 When closing the service panels take care that the tightening
torque does not exceed 4.1 Nm.
Prepare a water drainage channel around the
I
foundation to drain waste water from around the unit.
I If the unit is to be installed on a roof, check the
strength of the roof and its drainage facilities first.
If the unit is to be installed on a frame, install the
I
waterproofing board within a distance of 150 mm
under the unit in order to prevent infiltration of water
coming from under the unit.

Connecting the refrigerant piping

1
EFRIGERANT PIPING
All field piping must be installed by a licensed refrigeration
technician and must comply with relevant local and
national regulations.
NOTE Use R-407C only when adding refrigerant.
I
Installation tools:
I
Make sure to use installation tools (gauge
manifold charge hose, etc.) that are exclusively
used for R-407C installations to withstand the
pressure and to prevent foreign materials (e.g.
mineral oils such as SUNISO and moisture) from
mixing into the system.
Vacuum pump (use a 2-stage vacuum pump with
a non-return valve):
- Make sure the pump oil does not flow
oppositely into the system while the pump is
not working.
- Use a vacuum pump which can evacuate to
-100.7 kPa (5 Torr, -755 mmHg).
Installation of refrigerant piping is possible as front connection,
side connection and bottom connection.
